2.3. Unrivaled Flexibility
2.3.1. Frame Rates
It goes without saying that a modern high-end system camera has to support all
current HDTV-formats and has to be open for future (HD) formats, even though the
discussion about how the future HD format will look like has not been finished yet.
Let´s have a closer look to the HD formats and the way these are currently
implemented into the HDC-2500-series:

The above matrix clearly shows that the HDC-2000/-2500 models are featuring all
current and future HD-frame rates as a standard whereas HDC-2400/-2400DF and
HDC-1700 can be upgraded by software options if needed (refer to Picture 3/ next
page). Thanks to its wide bandwidth within the fibre transmission path, such high
data rate signals can be transmitted natively, without using any compression
technology.
The new
HDC-2570
with its digital triax transmission system can handle high-bitrate
signals, too. This camera employs Sony’s unique LLVC codec technology (LLVC =

odec) allowing to transmit either 1080P or 2xSloMo signals over
triax cable. Moreover, latency of the codec is very low (below one field; i.e. under
20ms) so that real live broadcasting is no issue.
New: all above noted framerate options are now available on a permanent, monthly
and weekly basis.
